Corrective Maintenance
Corrective maintenance refers to changing or replacing an element of the
system that is faulty. The MGC+ has several components in which problems
may occur:
• ReadiManager IAM

• Audio+ Modules
• Video+ Modules
• Data Modules
• I/O Cards
• Power Supply Module

Before replacing parts:
• To ensure a part needs replacing, complete the troubleshooting
procedures.
• Identify exactly which part needs replacing.
• Make sure you have the correct replacement part on hand.
• Make sure you are using proper ESD equipment, to prevent damage to
the system.
Warning!
• All maintenance tasks are to be performed by qualified, authorized
personnel.
• Use only replacement parts supplied by your dealer.
• Follow all procedures. Do not skip any steps.
Unless specified differently, the procedures described here are the same for
both the MGC+100 and the MGC+50.
